Tracking both?advanced missile threats and adversarial satellites is now paramount to national security. Currently, American space agencies have 10 hypersonic and ballistic missile tracking satellites in orbit. Yet, the U.S. plans to heavily invest across various solutions aimed at helping detect advanced missile and satellite threats. Earlier this year, the DoD confirmed Russia was testing a nuclear-capable satellite. As stated by Audrey Schaffer, vice president of strategy and policy at?Slingshot Aerospace, a California-based space technology firm, “The amount of traffic in space is only growing… when you have not just 10,000 satellites that are active but 10,000 satellites in a single constellation, it is very quickly going to be impossible for humans or even teams of humans to sift through all that data and identify potential threats to our national security.” Noteworthy developments indicating an arms race in space include: ·On June 14th, the Missile Defense Agency’s advanced missile tracking satellites logged their first views of a hypersonic flight test- a key step in validating American ability to track adversarial missiles. Eventually, the U.S. plans for this constellation to total over 100 satellites to provide global coverage of advanced missile launches. ·Slingshot Aerospace is developing an AI system that identifies anomalous satellites within large constellations. The company unveiled its model, dubbed #Agatha, on June 5, announcing that it had demonstrated the ability to detect outlier satellites among operational constellations. ·Later this year, a partnership between the U.S. Space Force and Rocket Lab, dubbed Victus Haze, will test American ability to rapidly deploy and position?satellites?in space to respond to threats and investigate suspicious objects. Where do you think the space arms race will take us? #space #spacerace #satellites #hypersonic #defense #armsrace

Today in Asia Times, I wrote about China's potential development of laser-equipped submarines capable of targeting satellites from underwater. This groundbreaking technology could revolutionize anti-satellite warfare by enabling stealthy attacks on adversary satellites, like SpaceX's Starlink, without revealing the submarine's position. These submarines could use a retractable mast to fire lasers and then dive to evade detection, presenting a significant strategic advantage in maintaining operational security and surprise in conflict scenarios. The proposed submarines could enhance China's capabilities in various military tasks, including anti-submarine warfare, protecting merchant vessels, and striking land targets. Nuclear-powered submarines are particularly suited for this role due to their ability to provide the necessary power for high-energy laser weapons. However, the effectiveness of these lasers against numerous small satellites and the potential risks of submarine exposure during operations remain areas of consideration.

'If a hostile nation from across the world would want to hit the US with a missile of some sort fast and decisively, then it'll likely give it a trajectory that heads over the northern polar region. That's because, given the nature of our globe and America's position on it, that's the shortest route possible. And it's also one of the most difficult to monitor with the satellites currently in space. The US knows this, and it already has a few cards up its sleeve to counter such a possibility. One of them is the Space-Based Infrared Systems (SBIRS) Highly Elliptical Orbit (HEO) network of satellites and associated systems. The network was introduced at the start of last decade, and served its purpose well until now. Chances are it will do so over the next decade as well, but it will eventually have to be replaced with something more capable and more in tune with the current technological advancements in missile technology. That something new is called the Next-Generation Overhead Persistent Infrared Polar (NGP), and it is the work of defense contractor Northrop Grumman. It's a fairly advanced project, as earlier in the summer, it completed the Ground Critical Design Review and Program Critical Integration Review.' https://lnkd.in/gcR5WmGc

An important development relating to the Missile Technology Control Regime (MTCR) with the Biden Administration issuing a new National Security Memorandum (see https://lnkd.in/gET5G39F) that eases constraints on the sharing of #space launch vehicle technology and technologies associated with long-range UAVs. This new guidance is important for #Australia's #space launch sector, as it allows greater access to US technologies to develop sovereign space launch related capabilities under Category 1 ('Cat 1') of the #MTCR. This should make it easier for Australian launch companies to make faster progress on developing new space launch technologies and allow greater Australian-allied integration of key space launch capabilities. It is important that the Australian government - both current and future - fully support Australia's commercial space sector, and especially sovereign launch capabilities such as those being developed by Gilmour Space Technologies, as well as launch sites such as those in development by companies such as Southern Launch, Equatorial Launch Australia (ELA) and Gilmour Space Technologies, as well as emerging providers including Space Centre Australia and Western Australia Spaceport.

I disagree strongly with this opinion piece in SpaceNews, specifically the author's assertion that kinetic counterspace weapons "may make sense in certain scenarios." They do not. The author postulates a scenario where "destroying?BeiDou?[Chinese GPS] satellites in medium Earth orbit would be unlikely to risk any U.S. or allied space assets, since there are?none?nearby." This is a very dangerous view of the problem. Such an attack would likely send the message that GPS satellites are open-season, but much of our civilian life relies on this constellation to function properly. An attack on GPS, which is part of our critical infrastructure, would have far-reaching implications because banks, internet APIs, and countless other IT systems require precision timing for operation and in some cases this comes from GPS. First responders, cargo vessels, and even the Amazon delivery guy all rely on GPS navigation signals to get from A-to-B. And GPS satellites are not replenished easily or quickly. I do not believe we should advocate for a policy that sends the global economy back to the analog age in a three-hour skirmish over some territory. Mustard and chlorine gases are pretty effective ways to disable enemy soldiers, but they are illegal. Cluster munitions have certain novel uses but they are banned by many nations due to their potential to cause harm to civilians. Kinetic counterspace weapons have indiscriminate effects which may go far beyond a debris field in a limited orbital regime, including the potential for significant responses that are difficult to de-escalate. Disabling or destroying missile warning satellites might cause the panicked receiving nation to retaliate with nuclear weapons... especially in an environment where communications with command centers are disabled or degraded. The author notes that the Army, Navy, and Air Force have few restraints on kinetic effects so why do the Guardians?! But if you sink a ship or shoot down a plane, the resultant effects are generally limited to the small area where the equipment lands. If you start taking out satellites it causes cascading effects like when you take out a power plant and it shuts down the water pumps and sanitation systems (see also: Operation Desert Storm). The author also posits that "taking a new look at assumptions about space-to-ground weapons — such as constellations designed for orbital kinetic bombardment — would prove worthwhile." I'm actually shocked that SpaceNews would run this piece. I don't even have words to describe what a terrible idea this is. Pre-positioned orbital weapons would allow global strike with almost no warning which sounds sweet if you're playing an online video game but it would cause all militarized nations to seek a counterattack to THAT. We're probably better served to avoid big red buttons that kill everyone on the planet.

Day 2 : Unique Learning SBIRs Satellite Systems The Space-Based Infrared System (SBIRS) is a United States Space Force program that provides early missile warning, missile defense, and technical intelligence. SBIRS is a constellation of satellites equipped with infrared sensors that can detect and track missile launches worldwide. The system is designed to enhance national security by providing timely and accurate information about missile threats. Key Components of SBIRS: 1. Geosynchronous Earth Orbit (GEO) Satellites: These satellites are positioned at high altitudes, allowing them to continuously monitor large areas of the Earth. They provide persistent coverage and can detect missile launches and other infrared events. 2. Highly Elliptical Orbit (HEO) Sensors: These sensors are carried on satellites in highly elliptical orbits, providing coverage of the polar regions, which are not covered by GEO satellites. 3. Ground Segment: The ground segment consists of control and data processing facilities that manage the satellites and analyze the data they collect. This includes command and control centers, as well as data relay stations. 4. infrared Sensors: The core technology of SBIRS is its advanced infrared sensors, which can detect the heat signatures of missile launches. These sensors can track the trajectory of missiles and provide critical data for missile defense systems. Functions and Applications: - Missile Warning: SBIRS provides early warning of ballistic missile launches, enabling prompt defensive measures. - Missile Defense: The system supports missile defense operations by providing tracking data that can be used to intercept and neutralize threats. - Battlespace Awareness: SBIRS contributes to situational awareness for military operations, helping to track and analyze various activities. - Technical Intelligence: The system collects data that can be used for intelligence purposes, such as assessing the capabilities of foreign missile systems. SBIRS represents a significant advancement in space-based surveillance and reconnaissance, providing critical information to protect national and global security. #nasa #jpl #lockheedmartin #space #ai

Let me elaborate a bit on why a space-based missile interceptor system doesn't scale well with the threat. To be clear, I'm NOT saying that space-based interceptors are technically infeasible (because they aren't) and I'm NOT saying we can't afford such a system (because we can). I'm just pointing out the problem of how the system scales relative to the threat--it's a matter of physics, not politics or budgets. And for the nerds, my specific assumptions in the model are at the bottom. You could of course house multiple interceptors together in one spacecraft, but the cost of the system is still driven by the number of interceptors, even if 5, 10, or 100 interceptors are housed together. Each interceptor requires a "kill vehicle" with sensors and avionics that can hone in and strike a missile during boost phase, and it needs a thruster capable of accelerating the kill vehicle to reach the missile in time. If you assume the dry weight (i.e., without propellant) for each interceptor is about 50 kg, accelerating it to reach a missile in boost phase would require about 741 kg of propellant (using the assumptions below). The interceptor would also need a "garage" to house it on orbit for basic station keeping, command and control, power, etc., which I assume would be about 100 kg. So each individual interceptor would weight about 800 kg + 100 kg for the garage. If you house five of them together, the garage would probably be less than 5 * 100 kg, but the mass of the interceptors would still be 5 * 800 kg. The most expensive part of the system is the interceptor's kill vehicle (sensors, avionics, thrusters, etc.), and you still need five of those even if you house five interceptors together. The launch costs also scale with the total mass of the system, which is driven by the number of interceptors--and propellant mass in particular is the main driver. To put this in perspective, launching a constellation of ~1,900 interceptors would mean launching a total of 1,400 metrics tons of propellant (likely toxic hydrazine because it is storable on orbit). That's enough to intercept a salvo of just two missiles launched at once from any location. If we want to protect against an adversary launching four missiles at once, we need to launch a constellation of 3,800 satellites with a total propellant mass of 2,800 metric tons. This why I say that a space-based interceptor system does not scale well with the threat. Here are my assumptions: Altitude of interceptor constellation: 500 km Height of missile at intercept: 200 km Time to intercept during boost phase: 150 seconds (very generous!) Max acceleration of interceptor: 10 g's Delta-V of interceptor: 4 km/s for flyout + 2.5 km/s for terminal maneuver Thruster ISP: 240 s Dry mass of interceptor: 50 kg Interceptor garage: 100 kg Note: my model is based on this APS study from 2004: https://lnkd.in/ekGFMmGb
